This sentence is profound and really highlights the sharp contrast between the few who choose their dreams and so many who choose wealth. When people are busy with their fame, status and wealth, their dreams are not worth mentioning. Most people give up looking up at the moon in the sky and choose to lower their heads to pick up sixpence on the ground. Sixpence is more important than the moon in the order of life, and natural selection of sixpence is more beneficial to oneself. Those warriors who choose the moon are so small and isolated in the crowd that they can't get the understanding of their family and friends, are ridiculed by others, and have many difficulties moving against the mainstream of society. Nevertheless, some people give up everything to find their own moon. It requires not only courage, but also perseverance. To be a man running to the moon, we must be prepared for a single thought.
